HMAS ''Hawkesbury'' (M 83), named for the Hawkesbury River, is the second to have been built for the Royal Australian Navy (RAN). Built by a joint partnership between Australian Defence Industries (ADI) and Intermarine SpA, ''Hawkesbury'' was constructed at ADI's Newcastle shipyard, and entered service in 2000. ==Design and construction== (詳細はBay class minehunters. The tender was awarded in August 1994 to Australian Defence Industries (ADI) and Intermarine SpA, which proposed a modified ''Gaeta''-class minehunter.〔 ''Hawkesbury'' has a full load displacement of 732 tons, is long, has a beam of , and a draught of .〔Saunders (ed.), ''IHS Jane's Fighting Ships 2012-2013'', p. 33〕 The ship's main source of propulsion is a single Fincantieri GMT BL230-BN diesel motor, which provides to a single controllable-pitch propeller, allowing the ship to reach .〔Wertheim (ed.), ''The Naval Institute Guide to Combat Fleets of the World'', p. 23〕 It has a maximum range of at , and is able to stay at sea for 19 days.〔〔 The standard ship's company consists of six officers and 34 sailors, with accommodation for nine additional personnel who are typically trainees or clearance divers.〔 The vessel's main armament is a MSI DS30B 30 mm cannon, which is supplemented by two 0.50 calibre machine guns.〔 Its sensor suite includes a Kelvin-Hughes Type 1007 navigational radar, a GEC-Marconi Type 2093M variable-depth minehunting sonar, an AWADI PRISM radar warning and direction-finding system, and a Radamec 1400N surveillance system.〔 Two Wallop Super Barricade decoy launchers are also fitted.〔 For minehunting operations, ''Hawkesbury'' uses three Riva Calzoni azimuth thrusters to provide a maximum speed of : two are located at the stern, while the third is sited behind the variable-depth sonar.〔 Mines are located with the minehunting sonar, and can be disposed of by the vessel's two Double Eagle mine disposal vehicles, the Oropesa mechanical sweep, the Mini-Dyad magnetic influence sweep, or the towed AMASS influence sweep (which is not always carried).〔 To prevent damage if a mine is detonated nearby, the ships were built with a glass-reinforced plastic, moulded in a single monocoque skin with no ribs or framework.〔 As the ships often work with clearance divers, they are fitted with a small recompression chamber.〔 ''Hawkesbury'' was built by Australian Defence Industries in Newcastle, New South Wales, launched on 24 April 1998, and commissioned into the RAN on 12 February 2000.〔 ''Hawkesbury'' is based at Sydney naval base HMAS ''Waterhen'', along with the majority of the RAN's mine warfare assets.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HMAS Hawkesbury (M 83)」の詳細全文を読む スポンサード リンク
